ET500lp C 25 mm Dia. Sputter Hard Coated; Longpass Filter
The ET500lp is a Longpass Filter, designed and manufactured by Chroma, a leading vendor in the optical industry. This filter is part of the UVFS MAL-1965 material ID family and features a circular base shape with a diameter of 25 mm and a thickness of 1 mm. The filter's primary function is to allow light with wavelengths greater than or equal to 515 nm to pass through while blocking shorter wavelengths.
The ET500lp filter boasts a cut-on wavelength of 500 nm, indicating that it begins to transmit light at this point along the spectrum. Conversely, it has a cut-off wavelength of 0 nm, meaning it blocks all wavelengths shorter than its cut-on point. This filter is coated on both the front and back with Chroma's ET500lp coating, enhancing its performance and durability.
The filter's physical data reveals that it is designed for use as a Thin Lens, suggesting that it can be used to focus or diverge light beams in optical systems. The filter is currently in stock and available for purchase through Chroma's official website, as indicated by its valid weblink status.
